For something on the casually edgy side, consider this combo of a charcoal crew-neck sweater and violet shorts. Introduce oxford shoes to this look to immediately boost the style factor of any outfit. This getup isn't a hard one to nail and it's summer-ready, which is important when it's blazing hot outside. In your 30s, you probably want to start dressing more maturely. If that's the case, combos like this become a great source of inspo.
